Be it known that I, -H.&nnr RUBIN, a citizen of the United'States,residing in the city of New York, county and' State of New York,haveinvented certain new and useful Improvements in Gas-Lamps, of whichthe following is such a full, clear, and exactdescription as willenablevany one skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming partof My mvention relates to lamps f or burning vordinary illuminating gasand the present improvements are more particularly appli cable tomultiple burner lamps in which incandescent mantles are used and theprin-- cipal objects of the .invention are to reduce the number of.parts and thereby simplify the construct-ion of lamps of this type, andrender the same less expensive to manufacture. f

I have illustrated a type of my invention in the accompanying drawings,wherein:

To all it may concern: l i the threaded iendyoflfi-the inner end of whi':l:1L ll-atte'r is screwed into? a I threaded perforation let-"formedinithe side of valve casing 5. Thfe'outer end'ot'the stop 12 is stopeither for the purpose of removing it or for increasing the tension onthe spring washer 16, the forked end of which embraces an annular groove17 near the outer 'end of the gas cock 7 while the'elongated end is theexterior of the valve casing 5 and thereby Byturning down the stop 12the tension on the spring washerlfi is increased and serves the tensionon the spring washerand cause the gas cook to turn easier, as may bedesired; By. this arrangement, I dispense with the ordinary screw andwasher carried upon the inner end of the seen that the stop 12 whilefixed in relation to the arms 8 and 9 of the gas cock, is adjust-ableangularly on its axis for the purpose washer ofthe gas cock and in thisway it serves a double function. It will also be noted that the screwthreaded pin 13, in addition to serving as a mounting for the stop 16 inposition by reason of passing through theqperforation 19 in the washer.This screw threaded pin 13 also serves as a removable closure'for thelateral opening 14: which'communicates with the central duct 6 of thevalve casing and is in alinement with the axis of the pipe section 1, inorder that access may be given to the interior of the pifi; sectionWhen-the pin 13 is removed,

The upper end o-fthe valve casing 5 is provided with a threaded plug 20which may be removed for the purpose of cleaning the central duct- 6 of.the valve casing. On its lower end the valve casing 5 is connected tothe airchamber 721 by means .of a threaded nipple22 in which is arrangeda needle valve 23 for regulating -.the jet openwhich operates shutter 25for regulating the" g nantit{ :of air admitted to the air if 1e innerend ofthe valve chains hambbr.

. provided with a slot 15 for receiving the end of a blade orjscrewdriver'ifor turning the of regulatlng the tension on the spring 12',alsofserves to maintain the spring washer i'ug'ythrough whiehIthe gaspasses. into the air. chamber. The air chamber 21. is *pro-' vided ,withlateral perforations 21 over? 2l is""'hreaded uponthe interior andrefcei'ves the threaded end of a coupling piece pipe section 27 thelower end of which extends downwardly in substantially verticalalinement with the supply pipe 1. Upon the lower end of the curved pipesection 27 is mounted by means of screw threads the tu- -bular bracket28 which in the present instancehas four branches each carrying a nipple29 upon each of which is removably placed a refractory burner 30, whichcarries an inverted incandescent mantle 31. The gang of burners; isprovided with a pilot light 32 which extends from a suitable point inthe valve casing 5 where it is in communication with a passage 33connected with the central duct 6 of the valve casing and from which itreceives its supply of gas fer the pilot, the flow of such gas. for thepilotbeing regulated by a screw valve 34 extending through the side ofthe valve casing' and having its conical end projecting into the mouthof the passage way 33 as indicated in Fig. 3. The casing forthe lampcomprises a tubular part 35 made of suitable material and this forms thechimney or flue for the products of combustion from the burners whichlie a slight distance below the lower edge of the casing. The lower endof the casing is slightly enlargedand isformed with an external shoulder36 over which extends the upper end of the annular hood '37 having theoutlet-openings 38-and the lower end of which is adapted to receive andsupport the glass globe 39, which incloses-the burners. The casing 35 issupported by means of an interior bracket 40 which is secured by meansofbolts 41 to the interior of the easmg and is provided at its upper andlower ends respectively with the supporting arms 42 and 43 the upper oneof which is perforated at 44 to receive the curved elbow 2 and the lowerone of which is perforated at 45 to receive the lower end of the curvedpipe section 27, which as before stated is in vertical alinement withthe gas supply pipe -1 and the upper end of the connected elbow 2. Thelower end of the pipe sect-hm is threaded upon the exterior and on thisthread is placed ascrew collar 45*, and this collar rests upon the upperside of the sup- ,porting arm 43 so as to afiord a substantial supportto the pipe section 27 and'it's connected parts. This bracket 40 inaddition to supporting the lamp. chimney, also maintains the supply pipeand the pipe section 27 'in central vertical position within, he lampcasing 35, theside of which is/ provided with an opening l6 for thepassage therethrongh of the gas pipe 4 and also with an opening 47 for.the passage of the short pipe coupling 26, the latter being providedwith washers 48 and 49 upon opposite faces of the wall of the casingwhich make a tight joint When'the pipe coupling 26 is screwed down hardinto the threaded end of the air chamber 21, as hereinabove described.This arrangement also serves to clamp the coupling 26 with its connectedparts firmly to the lamp casing. As the pipe section 4 also has a firmbearing on the lamp casing '35 these together with the firm mbunting ofthe coupling 26 gives stability to the valve casing 5 which is supportedby these parts. he upper end of the casing or chimney 35 which is 4enlarged and made ornamental upon its exterior is provided with acrosspiece 50 having a perforation through which passes the gas pipe 1and this serves to give lateral support to the upper end of the chimney.

The gas pipe. 1 is provided near its upper end with an externalscrewthread u on which is screwed a ,collar- 51 and aheat ell 52 havinga central perforation is placed over the'gas pipe which extends throughthe perforation so that the bell rests upon the collar 51. A nut 53is-then placed over the gas pipe and screwed down against the upper sideof the bell 52 and holds the same in fixed position.

It will be notedfihat the head or bracket 28 with its several radiatingarms is a single casting and thus provides a very simple form of burner. The upper side of the bracket where it is attached to the curved pipesection/ 27 is formed with a boss or short extension 54 against whichrests the under side" of the arm 43 of the supporting bracket ,40. l

- F rom the above description the operation of the/lampwill be readilyunderstood and briefly described it is as follows: The gas passingthrough pipe 1 is led to the valve cas ing 5 through the elbow piece 2and the pipe section 4 and flows into the central. duct dot the valvecasing. The Cook 7 being opened the gas passes through the central duct6 and by way of the needle valve into the air chamber where after beingmixedwiththe air it flows through the coupling 26, thence through thecurved pipe section 27 to the bracket 28 from where it is delivered tothe burners.

I find that a lamp constructed in this snnple manner and ofcomparatlvely few parts is a very efliclent one for illuminatingpurposes and that the cost of producing such a lamp is considerablyreduced.

he supporting bracket 40 secured between the chimney and the gas supplyand delivery pipes, affords a very substantial structure by reason ofthe fact that the upper arm 42 of the bracket engages the elbow 2 of thesupply pipe while the lower arm 48 engages the delivery pipe section 27and is clamped between the collar 45 on the pipe side of said chimney.andconnecte i said chimney and provided with a valve, a gas I ing,

section, and the boss 5 on the burner head 28. This constructionprovides two points of supportior the bracket at a considerable distanceapart and in this way a strong support is given the chimney in itsmounting upon the pipes.
